T 0. all w ham 2'2. may concern Be it known that I, AUeUs'r Sorrnrrnn, a citizen of the United States, residingat Columbus, in the county of Franklin and State ofOhio, have invented a certainnew and useful Improvement in Stoves, of which the following is a specification.

Gas heating stoves as at present in common use are enormously wasteful of heat. The object of the present invention is to provide means for conserving and utilizing much of such heat and the invention con sists in a modification of such stoves and the provision of means whereby a large part of the heat is stored and the necessity for the continuous consumption of fuel avoided.

The invention is embodied in the example herein shown and described, the features of novelty being finally claimed.

In the accompanying drawing Figure 1 is a vertical sectional view on the line II Fig. 2. r

Fig. 2 is a top plan view with a part broken out.

Fig.3 is a horizontal section on the line IIIIII Fig. 1. j V

Fig. 4L is a detail section of the burner on a larger scale. 7 I r In the views 5 designates the body of the stove which is generally of sheet metal and has its fire plate 6 inclined with its upper portion nearer the front so that its rear side shall form a seat for aremovable slab 7 of Y plate and slab heat the same.

soap-stone, fire clay orother refractory heat absorbing material. Said slab is substantially coextensive'in facial area with the back of the fire plate. Hinged at 8 is a hood 9 fitting upon and covering the upper end of said body portion. Within the said hood are small brackets 10 forming a seat to re ceive a removable slab 11 of material like that used to form the slab 7 and said slab is of a size to fit rather closely within the boundaries of the hood. The brackets 10-are so located that the slab ,11 lies in such spaced relation to the upper end of the fire as to provide room for the passage of the flame and products of combustion between the slabs and against the under side of the slab 11 so as to thoroughly 7 The cross plate that the top of the front of the stove serves to direct the flow of such productsto such passage. The hood has hinged to its upper end a cover 12 so that the slab 11 may be removed or a cooking vessel 13 or other obcover. is providedv with a latch at 12.

ject to .beheated placed upon the slab. The 14: designates the outlet for the products of combustion. i This is placed low on the back of the stove so that the products of combustion shall be caused to flow downward across the back'of the slab 7 as indicated by the arrows. Said outlet 14 contains a damper le -to shut off the escape of heat up the chimney .when the fire is extinguished. The slab 7 receives heat from both sides. If, after the fire is extinguished, it is desired to permit the heat from the slabs to come abundantly into the room the hood with the'slab 11 is turned backward to rest'on a bracket 15 as indicated by broken lines Fig. 1.=

The slabs? and 11 are each provided with a hole as seen at 7 and 11 respectively to receive an instrument, as for example the'end of an ordinary stove poker for the purpose of lifting them from the stove. The occasion for such removal would be in a mild season as when the weather becomes suddenly warm and much heat is not desirable. The ordinary gas burner includes in the present instance the gassupply pipe 16 placed as usual to discharge gas through burner holes 17 in the upper wall of the bottom chamber of the stove along and near the lower edge of the fire plate 7.

When the slabs are of suitable size they absorb large quantities of heat and give it ofi gradually. Therefore upon retiring'at night the fire may be extinguished with the v specification of Letters IEatent. Patent dJ '7 1921 assurance that the room will be kept eomfortable until the morning.

The forms of the parts can be changed without departing from the gist of the invention as claimed What I claim is:

1. A stove including in combination, a"

body havinga burner, a fire plate the back of which forms an upright seat for a slab, a removable slab on said seat, a hood having a seat for a slab, a slab of heat absorbing material on that seat, said seat being in spaced relation to the upper end of the first mentioned seat, said body provided with a vent in its rearbelow the upper end of the first mentioned seat whereby the products of combustion are deflected by the second mentioned slab across the back of the first mentioned slab.

2. A stove including in combination, a body having a burner, a fire plate the back of which forms an upright seat for a slab, a removable slab, heat absorbing material on said seat, a hood having a seat for a removable slab, said seat being in spacedrelation to the upper end of the first mentioned seat, a slab of heat absorbing materialon said seat, said body provided with a vent in its rear below the upper end of the first mentioned seat whereby the, products of combustion are deflected by the second mentioned slab across the back of the first mentioned slab, and a removable cover for said hood.

3. A stove including, in'combination, a

body having a burner, a fire plate the back 15 of which forms an upright inclined seat for a slab, a removable solid slab of heat absorblng material on said seat, a removable closing hood for the stovein spaced relation to said seat, said body provided 20 AUoUs-r sornxrrma.
